DETAILED DESCRIPTION
(32) FIG. 1 shows container 1 according to the invention with a jacket-shaped bottle body 2, which—as can be seen in FIG. 1a—comprises an upper container opening 3 and a lower container opening 4. A bottle teat 5 is fastened on upper container opening 3 with the aid of a sleeve cap 6 constituted as a connection part. A valve insertion part 7 is provided at lower container opening 4, which valve insertion part is fastened with the aid of a lower bottom cap 8. A cover cap 6a can also be seen, which is snapped onto sleeve cap 6 especially when the baby bottle is not in use and closes the drinking opening(s) of bottle teat 5 in a sealing manner in the snapped-on position.
(33) Bottle body 2 is shown in detail in FIGS. 2, 2a and 3, wherein it can in particular be seen that bottle body 2, in a region adjacent to upper connection opening 3 or lower connection opening 4, comprises in each case a plurality of grooves 12, four in the example of embodiment shown, which run essentially along a longitudinal extension plane perpendicular to a longitudinal axis 2′ of bottle body 2. These grooves 12 are intended to receive engaging elements 10, which are provided at the inner face of a skirt of sleeve cap 6 and bottom cap 8 (see in particular FIGS. 6a and 10).
(34) These spring-mounted engaging elements 10 are received—as can be seen in particular in FIG. 1a—in the grooves 12 in the connected position, so that sleeve cap 6 and bottom cap 8 are each in a snap-in connection with bottle body 2. The contact faces of engaging elements 10 or of grooves 12 can comprise undercuts, preferably at an angle of approximately 5°-15°, in order to reliably prevent an undesired release of the snap-in connection even in the presence of fairly great tractive forces acting in the longitudinal direction of container 1.
(35) In order to be able to release engaging elements 10 again from the connection shown in FIG. 1a, bottle body 2 and connection parts 6, 8 comprise run-on elements 9a, 9b.
(36) When connection part 6, 8 is rotated against the snapped-in position, in which engaging elements 10 are received in a receiving portion 14 of respective groove 12, engaging elements 10 are moved over an inclined run-on ramp 14a out of receiving portions 14 of grooves 12 and are then displaced towards one another in longitudinal direction 2′ of bottle body 2 with the aid of inclined run-on surfaces 9c of run-elements 9a, 9b, the run-on surfaces 9c running onto one another, so that engaging elements 10 are then arranged, viewed in longitudinal direction 2′, above or below adjacent grooves 12. Engaging elements 10 are located here during the displacement in longitudinal direction 2′ in an intermediate region 12a between two adjacent grooves 12, in which the surface of bottle body 2 is essentially flush with the adjacent surface of remaining bottle body 2.
(37) It can also be seen in particular in FIG. 2 that container 1 comprises a guide element 15 which, viewed in the longitudinal direction, is arranged in region 12a between two grooves 12, so that a plugging-together in the direction of the longitudinal axis 2′ of bottle body 2, in which engaging elements 10 do not snap into grooves 12, is made impossible. If engaging elements 10 are in fact undesirably arranged precisely in alignment with regions 12a between two adjacent grooves 12, a run-on element 9b runs in each case on an inclined guide flank 17 of respective guide element 15, so that a rotation of container 1 or bottle body 2 and connection element 6, 8 towards one another is achieved and engaging elements 10 snap into grooves 12.
(38) As can also be seen in FIGS. 4 to 10, engaging elements 10 are preferably arranged in wall portions 19 which, in contrast with the essentially rotation-symmetrical circular course, project inwards from a jacket portion of connection part 6, 8, and their imaginary connecting lines essentially form a rectangle. As a result of this inwardly projecting shape diverging from the circular shape, projecting wall portions 19 together with engaging elements 10 are elastically deformed during the snapping-on. In the snapped-on position, wall portions 19 thus remain elastically deformed and, only when released from the snapped-on connection, return again to their unstressed position diverging from the circular shape.
(39) FIG. 11 shows an alternative example of embodiment of a container 1 according to the invention in the form of a baby bottle, wherein this baby bottle 1 also comprises a bottle body 2, which—as can be seen in particular in FIG. 12—comprises an upper container opening 3 and a lower container opening 4. Once again, a bottle teat 5 is fastened on upper container opening 3 with the aid of a sleeve cap 6. A valve insertion part 7 is fastened to lower container opening 4 with the aid of a lower bottom cap 8.
(40) In FIGS. 13 and 14, in an enlarged representation, sleeve cap 6 and respectively bottom cap 8 provided as connection parts of container 1, in particular, are shown in detail in the connected representation with bottle body 2. It can be seen here that sleeve cap 6 and bottom cap 8, each comprise engaging elements 10, which are spring-mounted and, in the fastened positions shown in FIGS. 13 and 14, each engage behind a web 11 in the region of upper and lower bottle opening 3 and 4, so that teat 5 and valve insertion part 7 are reliably connected to bottle body 2 by means of sleeve cap 6 and respectively bottom cap 8. Contact faces 11′ of engaging elements 10 and/or of webs 11 between engaging elements 10 and webs 11 preferably comprise undercuts in the shown receiving portion 14 of groove 12. Such undercuts can in particular form an angle of approximately 5-15° with respect to a right angle to the surfaces from which the engaging elements or webs project, so that an undesired release of the snap connection is reliably prevented even in the presence of fairly large tractive forces acting in the longitudinal axis of the container.
(41) As can be seen in particular from FIGS. 15 and 16, bottle body 2, in a region adjacent to upper connection opening 3 and also in a region adjacent to lower connection opening 4, in each case comprises a plurality of grooves 12, four in the example of embodiment shown, in the manner of a bayonet connection. Grooves 12 each comprise an end portion 13 having a ramp shape, that is, running obliquely to an orthogonal plane to a longitudinal axis 2′ of container 1 as well as a receiving portion 14 running essentially along an orthogonal plane to longitudinal axis 2′.
(42) End portion 13 comprises an opening 13′, wherein an introduction into this opening 13′ is however only possible in a rotational direction, i.e. orthogonal to longitudinal axis 2′ of bottle body 2. In order reliably to prevent an introduction into end portion 13 in the direction of longitudinal axis 2′, a guide element 15 is provided in each case in the direction of longitudinal axis 2′ above and below in a region adjacent to opening 13′.
(43) These guide elements 15 therefore prevent engaging elements 10 from being introduced into end portions 13 when a connection part 6, 8 is united in the direction of longitudinal axis 2′ of container 1. It is thus ensured that, when connection part 6, 8 is brought together with container 1 in the direction of longitudinal axis 2′, engaging elements 10 are not introduced into end portion 13 of grooves 12. On the contrary, in the case where the rotational alignment between connection part 6, 8 and container 2 is such that an engaging element 10 and a guide element 15 meet one another during the bringing-together in longitudinal direction 2′, the rotational alignment of connection part 6, 8 changes with respect to container 2. For this purpose, guide elements 15 each comprise guide flanks 17 at the side of a rounded tip 15′, which guide flanks cooperate with respective engaging element 10, more precisely corresponding contact flanks 18 (see also FIGS. 19, 20, 21 and 23). Engaging elements 10 thus slide along obliquely arranged guide flanks 17, so that connection part 6, 8 is rotated with respect to the container or bottle body 2, until engaging elements 10 each strike against web 11, above or below which they then snap in in respective receiving portion 14 of respective groove 12. With a continued application of pressure in the direction of longitudinal axis 2′, engaging elements 10 pivot on account of their spring-loaded bearing and snap in behind respective web 11. In the transition region between the end portion and receiving portion of groove 12, a securing web 16 running transversely to the longitudinal extension of groove 12 is provided in each case, which securing web can only be overcome with the application of an increased rotational force. As a result of the overcoming of securing webs 16, it can thus be recognised by the user that the connection has been released.
(44) As can further be seen in FIG. 16, web 11 comprises a recess 13″ in a portion adjacent to opening 13′ of an adjacent groove. This recess 13″ forms a kind of receiving pocket in the region of opening 13′, so that, insofar as an engaging element 10 should come into contact in this region, a rotation into opening 13′ is prevented. With further application of a force in longitudinal direction 2′ of container 2, snapping-in by means of the snap connection thus takes place in this case.
(45) With regard to a spring-mounted bearing, engaging elements 10—as can be seen in FIGS. 19 to 23—can be arranged projecting inwards in particular on a circumferential wall 19.
(46) As can also be seen in FIGS. 19 to 23, inner circumferential wall 19 is constituted integral with the remaining connection part, i.e. sleeve cap 6 and bottom cap 8, wherein however inner wall 19 has a much smaller wall thickness compared to an outer wall 20, which produces the stability of the respective connection part. When the connection parts are produced from a thermoplastic plastic, e.g. polypropylene (PP), a wall thickness between 0.5 mm and 3.5 mm in particular has proved to be advantageous.
(47) Due to the relatively small wall thickness, the entire circumferential wall is thus easily elastically deformable. In order to ensure the easy snapping-over on associated web 11, the circumferential wall does not comprise a circular course in its unstressed position, but rather a course diverging from a circular shape, which course essentially corresponds to a square shaped with rounded corners in the example of embodiment shown. When engaging elements 10 pass over respective web 11, wall 19 carrying engaging elements 10 can thus essentially assume a circular shape, then to return again into the square shape diverging from a circular shape, shown in particular in FIGS. 19 and 21. Reliable snapping-in between respective web 11 and associated engaging element 10 is thus ensured.
(48) An alternative example of embodiment to this kind of spring-loaded mounting of engaging elements 10 is shown in FIG. 24. Here too, a container 1 with a bottle body 2 is also shown, on which a sleeve cap 6 and a bottom cap 8 are provided as connection parts.
(49) As can be seen in particular in FIGS. 25 and 26, it is also possible—as an alternative to a comparatively thin-walled elastic wall 19—for engaging elements 10 to be constituted on an outer wall 20, wherein in this example of embodiment engaging elements 10 are each arranged in the end region of detent tongues 21.
(50) Detent tongues 21 are again obtained by material recesses or cutouts 22 in outer wall 20. As can be seen in FIG. 24, a container 1 can also thus be connected to two connection parts 6, 8, which are connected either by a snap connection produced in longitudinal direction 2′ or, however, by an insertion/rotation connection with flange body 2 shown in particular in FIGS. 15 and 16.
(51) FIGS. 17 and 18 show in detail a bottle teat 5 and insertion part 7 [[8]], which are constituted specially for use with sleeve cap 6 and bottom cap 8.
(52) Bottle teat 5 comprises here in a cylindrical end portion 25, which in the assembled position comprises a slightly larger inner diameter compared to an outer diameter of bottle body 2 in the region of upper container opening 3, as can be seen in particular in FIG. 13.
(53) It can further be seen in FIG. 17 that bottle teat 25 comprises a circumferential groove 25′ at the upper side of a fastening flange 25″. As can be seen in particular in FIG. 13, groove 25′ is arranged essentially congruent with an edge of upper container opening 3. When connection part 6 and container 2 are plugged together, teat 5 thus yields in a resilient manner in the region of groove 25′, so that, as a result of the pretensioning thus produced in the connected position shown in FIG. 13, contact faces 11′ of webs 11 and engaging elements 10 are pressed together by fastening flange 25″ and respectively groove 25′, so that in the connected state the contact faces reliably lie against one another.
(54) An analogous effect is achieved in the region of lower container opening 4 with the aid of insertion part 7. For this purpose, insertion part 7 in the region of a fastening flange 26″ at its underside comprises a groove 26′ (see FIG. 14), which in the connected state is arranged essentially congruent with an edge of lower container opening 4. When connection part 8 and container 2 are plugged together—with the interposition of insertion part 7—insertion part 7 thus yields in a resilient manner in the region of groove 26′, so that, as a result of the pretensioning thus generated in the connected position shown in FIG. 14, contact faces 11′ of webs 11 and engaging elements 10 are pressed against one another by fastening flange 26″ and respectively groove 26′.
(55) It can further be seen in FIG. 13 that cylindrical portion 25 at its lower end comprises a circumferential sealing lip 27 tapering towards a free end and directed inwards, which sealing lip lies under pretensioning in a sealing manner against the outer surface of bottle body 2 in the upper end portion. If the pressure difference between the interior of container 1 and the surrounding environment should increase, sealing lip 27 is thus pressed with increased pressing force on the outer surface of bottle body 2, so that the sealing effect is increased depending on the pressure difference between the interior in container 1 and the ambient pressure.
(56) It can further be seen that cylindrical end portion 25 comprises a circumferential web 28 projecting upwards. This circumferential web 28 is essentially provided to cooperate with a web or web portions 29 at the underside of a cap portion 30 of sleeve cap 6. As can be seen in FIGS. 21 and 23, downwardly projecting web portions 29 of cap portion 30 of sleeve cap 6 are—in particular for deformation purposes—interrupted, so that in the example of embodiment shown four essentially circle segment-shaped web portions 29 result, which engage behind projecting web 28 on teat 5, so that undesired pulling out of teat 5 in the connected state between container 2 and sleeve cap 6 is not possible even in the presence of a relatively low contact pressure between sleeve cap 6 and container 2 in the direction of longitudinal axis 2′.
(57) In FIGS. 21 and 23 projections 31 are distributed around the circumference adjacent the web portions 29 in the transition region between the underside of cap portion 30 and inner wall 19, wherein in the example of embodiment shown three nub-like projections 31 are provided four times. These projections 31 are provided in order to centre bottle teat 5, i.e. despite the course of wall 19 diverging from a circular shape, in order reliably to position teat 5 centrally. Corresponding projections 31 are also provided, as can be seen in FIGS. 19 and 20, for the centering or exact positioning of insertion part 7 in bottom cap 8.
(58) Insertion part 7 represented in FIG. 18 for forming an air intake valve together with bottom cap 8 also comprises—as can be seen in particular in FIG. 14—a cylindrical end portion 26, which comprises a larger inner diameter than bottle body 2 in the region of lower container opening 4 at the outer surface. End portion 26 comprises—corresponding to bottle teat 5—a circumferential sealing lip 27 projecting inwards and tapering towards its free end, which sealing lip lies under pretensioning in a sealing manner against the outer surface of bottle body 2. The sealing principle already described in connection with the bottle teat 5 thus results.
(59) It can further be seen in FIG. 14 that insertion part 7 comprises a sealing lip 32, which enables an air intake in the presence of an underpressure in the interior of container 2, but which prevents an exit of liquid. In the example of embodiment shown, sealing lip 32 lies on an annulus-shaped upper platform 34 of an inwardly projecting dome-shaped recess 33 of bottom cap 8. As an alternative to the shown sealing seating of this circumferential sealing lip 32 on the platform 34, however, a seating of a sealing lip on the lower bottom portion of bottom cap 8 outside dome-shaped recess 33 is also possible, as well as a sealing seating at the outer side of the entire dome-shaped recess 33 of bottom cap 8.
(60) FIG. 27 shows a bottle body 2 of an alternative example of embodiment, which largely corresponds to the example of embodiment according to FIGS. 11 to 26, but in this example of embodiment the opening 13′ of end portion 13 of respective groove 12, shown in FIG. 15, is provided with a stop 35. In this example of embodiment, therefore, a connection of connection parts 6, 8 to container 1 by means of an insertion/rotation connection is thus not possible with the aid of stop 35—in contrast with the previously described examples of embodiment, but rather a connection between connection parts 6, 8 and container 1 is only possible by means of a snap connection. A release of the connection is of course once again possible—as described above—by means of a rotational movement, wherein respective engaging element 10 acts as run-on element 9b having a run-on surface 9c running on run-on surface 9c of run-element 9a for removing engaging element 10 from respective groove 12 via opening 13′. Since stop 35 has to be overcome, it is advantageous if stop 35 comprises a run-on ramp directed towards groove 12, in order to facilitate the removal of respective engaging element 10 from end portion 13. The other flank of stop 35, on the other hand, is advantageously arranged essentially at a 90° angle to the bottom of the groove, in order to prevent an undesired connection by a rotational movement.
(61) The invention has been described below in connection with a bottle container, in particular a baby bottle. Container 1 according to the invention or the fastening of a connection part 6, 8, which reliably takes place by means of a snap connection, can of course also be used in connection with other containers such as for example breast pumps, storage and transport containers in general and other food packages and suchlike, as well as containers in general.
